Multisensor PIR problem [solved]

@n3ro said:

yes :)
Serial.println(mytime);

[rvendrame]

#define PIR_SENSOR_DIGITAL 3           // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
#define INTERRUPT PIR_SENSOR_DIGITAL-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
#define HUMIDITY_SENSOR_DIGITAL_PIN 2
#define LIGHT_SENSOR_ANALOG_PIN 0

Are you connecting both DHT and PIR at same pin 2 ? That must be the cause (DHT is triggering the interruption, I think you want only the PIR to trigger it).

Edit: looks like your PIR is at pin 3 , and DHT on pin 2 --- Should be the inverse? The PIR should be on pin 2 (to trigger the interrupt).

[Sweebee]

@rvendrame Pir sensor is defined as 3

interrupt pin is defined as INT1: 3 - 2 = 1

[rvendrame]

So PIR must connect on PIN 1 and not PIN 3.

Edit: Better, how did you connect DHT and PIR?

[n3ro]

@rvendrame The DHT is on pin 2 and the pir on pin 3. i use the MYS PCB.

i suspect the delay function disturb the sleep function. if i dont use the delay, the dht cant "heat up".

far as I know the interrupt is only an internal value. right?

[rvendrame]

Yes, it looks fine. What exactly error are you having? From your first serial monitor, it looks like your sensor woke on every 10min aprox, ( 6608 / 11148 / 15441 ).

The DHT gives only output the first start and the pir interrupt works perfect.

When delay(dht.getMinimumSamplingPeriod()); is activated the DHT works and the pit interrupts the whole time :(
In this configuration the arduino never sleeps ..

EDIT: i have changed the sleeptime for testing to a shorter time

[Sweebee]

@rvendrame When the PIR is connected to PIN3 the interrupt is INT1. Pin 1 does not have an interrupt.

Only pin 2 and pin 3 have an interrupt.

Pin 2 = int0
pin 3 = int1

[rvendrame]

if you put the delay() inside that 'if ( mills() > mytime ) ' , what happens?

[n3ro]

@Sweebee is it possible to fix the problem when DHT is connected to pin 4?

[rvendrame]

@n3ro said:

It worth a try ...

[n3ro]

@rvendrame
i have posted it before this post:

"What is this number? Did you print the milis()?

send: 10-10-0-0 s=1,c=1,t=16,pt=0,l=1,st=fail:0

in the posted sketch the delay is inside millis

[Sweebee]

This can't work well. Your interrupt is set on pin1 - 2 = int-1?

What happens when you remove the pir and use a switch instead?

[n3ro]

@Sweebee
is #define INTERRUPT PIR_SENSOR_DIGITAL-2 wrong?

when i use a switch it looks OK

[rvendrame]

@n3ro , what is wrong at your last test? The PIR is reporting 0 and 1, and from time to time there is a temp/hum report as well.

[n3ro]

@rvendrame in my last test the pir sends endless 0 and dont sleep

[rvendrame]

Which arduino PIN do you use to connect the PIR?

[n3ro]

@n3ro said:

#define PIR_SENSOR_DIGITAL 3
